C# 以编程方式将客户端应用程序列表设置为WCF服务';s在运行时使用URL创建的端点(与WCF测试客户端类似)
也许我没有用正确的术语搜索,因为这看起来很简单。我只是在寻找一种方法来列出一个WCF服务的端点,该服务在运行时创建了它的端点,就像WCF测试客户端那样C# 以编程方式将客户端应用程序列表设置为WCF服务';s在运行时使用URL创建的端点(与WCF测试客户端类似),c#,wcf,C#,Wcf,也许我没有用正确的术语搜索,因为这看起来很简单。我只是在寻找一种方法来列出一个WCF服务的端点,该服务在运行时创建了它的端点,就像WCF测试客户端那样 指定URL 获取元数据和端点 这是我在运行时添加端点的方式 string SetInstrumentsURL = serviceUrl + "SetInstruments/"; string SetInstrumentsPipe = "net.pipe://localhost/TestService/SetInstruments/"; Ser

我可以从客户端使用哪些函数来访问与WCF测试客户端相同的端点?如果我已经有了端点的URL,我知道如何连接到这些端点,但我希望有一个端点列表,这样我就可以创建一个下拉列表,根据您连接到的主机的不同从中进行选择
通过Visual Studio添加服务引用不会列出所有端点,因为尚未创建。是一个库,我可以像WCF测试客户端一样在运行时获取它们。如果我们有服务元数据URI,我们可以使用System.ServiceModel.Description命名空间中提供的MetadataExchangeClientMode和MetadataResolver类来检索和处理元数据。
我举了一个简单的例子,希望对你有用。
class Program
{
static void Main(string[] args)
{
Uri uri = new Uri("http://10.157.13.69:3336/mex");
MetadataExchangeClient client = new MetadataExchangeClient(uri, MetadataExchangeClientMode.MetadataExchange);
MetadataSet metadata = client.GetMetadata();
WsdlImporter importer = new WsdlImporter(metadata);
ServiceEndpointCollection endpoints = importer.ImportAllEndpoints();
//ServiceEndpointCollection endpoints = MetadataResolver.Resolve(typeof(IService), uri, MetadataExchangeClientMode.MetadataExchange);
foreach (var item in endpoints)
{
Console.WriteLine(item.Address.Uri);
}
}
}
[ServiceContract]
public interface IService
{
[OperationContract]
string SayHello();
}
结果好的,这很容易做到,我只需要使用MetadataExchangeClient来获取配置。在代码中,获取元数据Xml所需的全部操作如下:
var meta = new System.ServiceModel.Description.MetadataExchangeClient(new Uri("net.tcp://10.0.2.124:9000/TeraService/SetInstruments/mex"), System.ServiceModel.Description.MetadataExchangeClientMode.MetadataExchange);
var data = meta.GetMetadata();
System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(data.GetType());
TextWriter writer = new StreamWriter("xmlfile.xml");
x.Serialize(writer, data);
writer.Close();
我把答案贴错了地方。但是Abraham Qian有一个更优雅的解决方案,我现在将对其进行测试。据我所知,我们可以使用ChannelFactory通过指定端点地址手动创建通信通道,然后调用服务。我们可以使用SVCUTIL.exe工具获得这些端点。我忘了补充一点,我正试图以编程方式获取这些端点,所以如果有一个C#库可以使用,那将是最好的。我觉得服务模型库应该有这样的功能。
